A sensing terminal and a receptacle are installed in a charge battery and a charger, respectively. During charging, a charging circuit within the charger will detect whether the battery is pulled out from the charger. If the battery is pulled out, the power source will be turned off in a very short time so that no voltage will be sent from the terminal of the charger in order to protect the charger. As the charge battery is pulled out from the charger, no spark is generated and the battery is prevented from being burned out.
